FIELD

The present disclosure relates generally to a filter assembly and moreparticularly to a filter assembly having a seal and a compression ring.

BACKGROUND

This section provides background information related to the presentdisclosure and is not necessarily prior art.

Various filter assemblies are known in the art for filtering fluid, suchas air, as it travels along a fluid path. Such filters include filtermedia which removes impurities from the fluid. In most applications,either the filter assembly or the filter media associated therewith mustbe periodically replaced to reduce the potential for developingunacceptably high impedance in the fluid flow path.

While known filter assemblies have proven to be acceptable for variousapplications, such conventional filter assemblies are neverthelesssusceptible to improvements that may enhance their overall performanceand cost. Therefore, a need exists to develop an improved filterassembly and methodologies for forming the same that advance the art.

DETAILED DESCRIPTION

Example configurations will now be described more fully with referenceto the accompanying drawings. Example configurations are provided sothat this disclosure will be thorough, and will fully convey the scopeof the disclosure to those of ordinary skill in the art. Specificdetails are set forth such as examples of specific components, devices,and methods, to provide a thorough understanding of configurations ofthe present disclosure. It will be apparent to those of ordinary skillin the art that specific details need not be employed, that exampleconfigurations may be embodied in many different forms, and that thespecific details and the example configurations should not be construedto limit the scope of the disclosure.

The terminology used herein is for the purpose of describing particularexemplary configurations only and is not intended to be limiting. Asused herein, the singular articles “a,” “an,” and “the” may be intendedto include the plural forms as well, unless the context clearlyindicates otherwise. The terms “comprises,” “comprising,” “including,”and “having,” are inclusive and therefore specify the presence offeatures, steps, operations, elements, and/or components, but do notpreclude the presence or addition of one or more other features, steps,operations, elements, components, and/or groups thereof. The methodsteps, processes, and operations described herein are not to beconstrued as necessarily requiring their performance in the particularorder discussed or illustrated, unless specifically identified as anorder of performance. Additional or alternative steps may be employed.

When an element or layer is referred to as being “on,” “engaged to,”“connected to,” “attached to,” or “coupled to” another element or layer,it may be directly on, engaged, connected, attached, or coupled to theother element or layer, or intervening elements or layers may bepresent. In contrast, when an element is referred to as being “directlyon,” “directly engaged to,” “directly connected to,” “directly attachedto,” or “directly coupled to” another element or layer, there may be nointervening elements or layers present. Other words used to describe therelationship between elements should be interpreted in a like fashion(e.g., “between” versus “directly between,” “adjacent” versus “directlyadjacent,” etc.). As used herein, the term “and/or” includes any and allcombinations of one or more of the associated listed items.

The terms first, second, third, etc. may be used herein to describevarious elements, components, regions, layers and/or sections. Theseelements, components, regions, layers and/or sections should not belimited by these terms. These terms may be only used to distinguish oneelement, component, region, layer or section from another region, layeror section. Terms such as “first,” “second,” and other numerical termsdo not imply a sequence or order unless clearly indicated by thecontext. Thus, a first element, component, region, layer or sectiondiscussed below could be termed a second element, component, region,layer or section without departing from the teachings of the exampleconfigurations.

With reference to FIG. 1, a filter assembly 10 is shown. As will beexplained in more detail below, the filter assembly 10 may be used forremoving impurities and/or particulates from a fluid passingtherethrough. For example, the filter assembly 10 may be used in avehicle (not shown), such as an automobile or commercial equipment, toremove impurities from air passing between the environment and an engineor motor of the vehicle. In this regard, the filter assembly 10 mayinclude an inlet end 12 and an outlet end 14. The fluid containing theparticulates may enter the filter assembly 10 at the inlet end 12, andclean air (e.g., air without the particulates) may exit the filterassembly 10 at the outlet end 14.

The filter assembly 10 may include a filter element 16 and a housing 18.As illustrated in FIG. 1, the filter element 16 may be disposed withinthe housing 18. In some configurations, the housing 18 includes a bodyportion 20 and a cover 22. In an assembled configuration, the cover 22may be removably coupled to the body portion 20 to define a chamber 24.In this regard, the cover 22 may be removed from the body portion 20 toprovide access to the chamber 24 and the filter element 16 disposedtherein.

The cover 22 may include a first support wall 26, a second support wall28, and an outer wall 30. The first and second support walls 26, 28 maybe disposed proximate the inlet end 12. In some implementations, atleast a portion (e.g., an inner surface) of the first support wall 26extends in a radial direction, while at least a portion (e.g., an innersurface) of the second support wall 28 and at least a portion (e.g., aninner surface) of the outer wall 30 extends in an axial direction. Inthis regard, the inner surface of the outer wall 30 may define a firstdiameter D1, while the inner surface of the second support wall 28 maydefine a second diameter D2 that is less than the first diameter D1.

The body portion 20 may include a third support wall 32 and a fourthsupport wall 34. The third and fourth support walls 32, 34 may bedisposed proximate the outlet end 14. In some implementations, at leasta portion (e.g., an inner surface) of the third support wall 32 extendsin a radial direction, while at least a portion (e.g., an inner surface)of the fourth support wall 34 extends in an axial direction. The innersurface of the fourth support wall 34 may define a third diameter D3that is substantially similar (e.g., equal to) to the second diameterD2.

As will be explained in more detail below, in the assembledconfiguration, the filter element 16 may be disposed within the chamber24 such that one or both of the first and second support walls 26, 28engage a first end of the filter element 16, while one or both of thethird and fourth support walls 32, 34 engage a second end of the filterelement 16, to secure the filter element 16 between the body portion 20and the cover 22 within the chamber 24.

With reference to FIGS. 1-4, the filter element 16 may include a filtermedia 36, a seal member 38, a screen element 40, a compression ring 42,and a plug 43. In some implementations, the filter media 36 includes afluted sheet secured to a flat sheet. The fluted sheet may include acorrugated layer secured to the flat sheet via an adhesive. Thecorrugated layer may include straight flutes, whereby the flutes areparallel to one another. The straight flutes may include crushed ends orpinched ends. In some implementations, the corrugated layer includestapered flutes, whereby alternating flutes gradually converge from awide section to a narrow section with the subsequent adjacent flutediverging from a narrow section to a wide section. While the filtermedia 36 is generally shown and described herein as defining a flutedsheet secured to a flat sheet, it will be appreciated that the filtermedia 36 may take other forms (e.g., pleated filter media) within thescope of the present disclosure.

In some implementations, the filter media 36 is wrapped in a coiledconfiguration. For example, the filter media 36 may be wrapped to definea substantially cylindrical shape. In other implementations, the filtermedia 36 may be wrapped to define other shapes (e.g., oval, oblong,rectangular, etc.). In some configurations, the filter media 36 iscoreless, whereby the filter media (e.g., the fluted sheets and the flatsheets) are disposed only around one each other or a hollow, and are notaround a central core member or other structure.

As illustrated in FIG. 4, the filter media 36 may extend along alongitudinal axis A1 and include a body 44 having a first end 46 and asecond end 48 spaced apart from and opposing the first end 46. Withreference to FIG. 1, in the assembled configuration, the first end 46may be disposed proximate the inlet end 12 of the filter assembly 10.The second end 48 may be disposed proximate the outlet end 14 of thefilter assembly 10. In this regard, as will be explained in more detailbelow, the first end 46 may correspond to an inlet for the flow of fluidthrough the filter media 36 and the filter assembly 10, while the secondend 48 may correspond to an outlet for the flow of fluid through thefilter media 36 and the filter assembly 10.

As illustrated in FIG. 4, the body 44 may include a outer side surface50 extending between the first end 46 and the second end 48. The outerside surface 50 may define a fourth diameter D4. The fourth diameter D4may be less than the second diameter D2. In some configurations, thebody 44 includes a ledge 52 disposed proximate the outlet end 14 of thefilter assembly 10. In some implementations, the ledge 52 is formed bycutting the body 44 of the filter media 36. For example, the ledge 52may be formed by cutting a channel into the outer side surface 50 andthe second end 48. In other implementations, the ledge 52 may be formedby wrapping the filter media 36 at varying positions along thelongitudinal axis A1.

The ledge 52 may define or otherwise include a top surface 54 and a sidesurface 56. The top surface 54 may be disposed between the first andsecond ends 46, 48. In some implementations, the top surface 54 extendsin a radial direction. The side surface 56 extends from the top surface54 and be disposed between the longitudinal axis A1 and the outer sidesurface 50. In this regard, the side surface 56 may extend in an axialdirection. The side surface 56 may define a fifth diameter that is lessthan the fourth diameter D4.

With reference to FIGS. 1, 3, and 4, the seal member 38 may include afirst end surface 58, a second end surface 60, an outer side surface 62,and an inner side surface 64. The second end surface 60 may be spacedapart from and opposing the first end surface 58. In someimplementations, the first and second end surfaces 58, 60 extend in aradial direction relative to the axis A1. The outer side surface 62 mayextend between the first end surface 58 and the second end surface 60.In some implementations, the outer side surface 62 extends in an axialdirection. In this regard, the outer side surface 62 may define a sixthdiameter D6. While the sixth diameter D6 is generally shown as beinglarger than the fourth diameter D4 of the body 44 of the filter media36, in some implementations, the sixth diameter D6 may be substantiallysimilar to (e.g., equal to) the fourth diameter D4. The inner sidesurface 64 of the seal member 38 may extend between the first endsurface 58 and the second end surface 60. In some implementations, theinner side surface 64 extends in an axial direction. In this regard, theinner side surface 64 may define a seven diameter D7 that is less thanthe sixth diameter D6. The seventh diameter D7 may be substantiallysimilar to (e.g., equal to) the fifth diameter D5 of the filter media36.

With continued reference to FIGS. 1, 3, and 4, in the assembledconfiguration, the seal member 38 may be disposed proximate the secondend 48 of the body 44 of the filter media 36. For example, the sealmember 38 may be disposed on the ledge 52 such that the seal member 38surrounds the second end 48 and the longitudinal axis A1. As illustratedin FIGS. 2 and 3, the second end 48 of the body 44 of the filter media36 may be disposed between the second end surface 60 of the seal member38 and the first end 46 of the body 44 of the filter media 36, while theouter side surface 50 of the body 44 of the filter media 36 may be flush(e.g., coplanar), or disposed radially outward of, the outer sidesurface 62 of the seal member 38. In this regard, the second end surface60 of the seal member 38 may extend proud of the second end 48 of thebody 44 of the filter media 36 in the axial direction, while the outerside surface 50 of the body 44 of the filter media 36 may be flush with,or extend proud of, the outer side surface 62 of the seal member 38 inthe radial direction. The seal member 38 may be formed of a compressiblematerial, such as rubber or plastic, for example. In someimplementations, the seal member 38 is formed of a polyurethane foam.

With reference to FIG. 1, when the filter assembly 10 is in an assembledconfiguration, the seal member 38 may directly engage the body portion20 of the housing 18. For example, the seal member 38 may engage one orboth of the third support wall 32 or the fourth support wall 34 of thehousing 18. In some implementations, the second end surface 60 of theseal member 38 directly engages the third support wall 32 of the housing18, while the outer side surface 62 of the seal member 38 is spacedapart from the fourth support wall 34 of the housing 18. In otherimplementations, the second end surface 60 of the seal member 38directly engages the third support wall 32 of the housing 18, and theouter side surface 62 of the seal member 38 directly engages the fourthsupport wall 34 of the housing 18. Engagement between the second endsurface 60 of the seal member 38 and the third support wall 32 of thehousing 18, and/or the outer side surface 62 of the seal member 38 andthe fourth support wall 34 of the housing 18, may provide a sealingarrangement that prevents or otherwise inhibits a flow of fluid from theinlet end 12 of the filter assembly 10 to the outlet end 14 of thefilter assembly 10 other than through the second end 48 of the filtermedia 36.

As illustrated in FIG. 4, the screen element 40 may include a baseportion 66 and an flange portion 68. The base portion 66 may define afirst end 70 and a second end 72. In some implementations, the baseportion 66 is substantially disc-shaped such that the first end 70and/or the second end 72 extend in a substantially planar direction. Thebase portion 66 may define an eighth diameter D8, that is substantiallysimilar to (e.g., equal to) the fifth diameter D5 of the filter media 36and the seventh diameter D7 of the seal member 38.

The flange portion 68 may extend from, and surround, the base portion66. In some implementations, the flange portion 68 extends from the baseportion 66 at an angle α. The angle α may be between five degrees andone hundred seventy-five degrees. In some implementations, the angle αis substantially equal (e.g., +/− ten degrees) to one hundredthirty-five degrees. The screen element 40 may be formed of a rigid orsemi-rigid material defining a plurality of apertures therethrough. Forexample, the screen element 40 may be formed from a mesh (e.g., metal,plastic, etc.) defining a plurality of apertures that allow fluid toflow through the base portion 66 in the axial direction relative to theaxis A1.

With reference to FIGS. 1, 3, and 4, in an assembled configuration, thescreen element 40 is disposed adjacent to the body 44 of the filtermedia 36. In particular, the first end 70 of the screen element 40 mayengage the second end 48 of the body 44 of the filter media 36. Asillustrated in FIGS. 1 and 3, in some implementations, the seal member38 is molded to the body 44 of the filter media 36 and/or the screenelement 40. In this regard, the seal member 38 may be overmolded to thescreen element 40 such that the seal member 38 encapsulates the flangeportion 68, thereby securing the screen element 40 to the body 44 of thefilter media 36.

As illustrated in FIG. 4, in some implementations, the compression ring42 includes a first end surface 74, a second end surface 76, an outerside surface 78, and an inner side surface 80. The second end surface 76may be spaced apart from and opposing the first end surface 74. In someimplementations, the first and second end surfaces 74, 76 extend in aradial direction relative to the axis A1. The outer side surface 78 mayextend between the first end surface 74 and the second end surface 76.In some implementations, the outer side surface 78 extends in an axialdirection relative to the axis A1. The outer side surface 78 may definea ninth diameter D9 that is substantially similar to, or larger than,the fourth diameter D4 of the filter media 36 and the sixth diameter D6of the sealing member 38. The inner side surface 80 may extend betweenthe first end surface 74 and the second end surface 76. In someimplementations, the inner side surface 80 extends in an axial directionrelative to the axis A1. The inner side surface 80 may define a tenthdiameter D10 that is less than the ninth diameter D9. The tenth diameterD10 may be substantially similar to (e.g., equal to) the fifth diameterD5 of the filter media 36, the seventh diameter D7 of the sealing member38, and the eighth diameter D8 of the screen element 40.

As illustrated in FIG. 2, in some implementations, the compression ring42 includes one or more channels 82-1, 82-2, . . . 82-n. In this regard,while the compression ring 82 is generally shown and described herein asincluding four channels 82-1, 82-2, . . . 82-n, it will be appreciatedthat the compression ring 42 may include more or less than four channels82-1, 82-2, . . . 82-n within the scope of the present disclosure. Insome implementations, the channels 82-1, 82-2, . . . 82-n are evenlyspaced about the compression ring 42.

The channels 82-1, 82-2, . . . 82-n may be formed in the first endsurface 74 and/or the outer side surface 78 of the compression ring 42.The channels 82-1, 82-2, . . . 82-n may extend in a radial and/or axialdirection. In this regard, each of the channels 82-1, 82-2, . . . 82-nmay be defined in part by an end surface 90 and a side surface 92. Theend surface 90 may extend in a radial direction, and the side surface 92may extend in an axial direction, such that the end surface 90 and theside surface 92 cooperate to define an L-shape. It will be appreciatedthat the end surface 90 and the side surface 92 may cooperate to defineother shapes within the scope of the present disclosure. As will beexplained in more detail below, during operation of the filter assembly10 the channels 82-1, 82-2, . . . 82-n allow fluid communication betweenthe first end 46 and the outer side surface 50 of the body 44 of thefilter media 36 and prevent the compression ring 42 from forming asealed relationship with, or relative to, the housing 18.

With reference to FIGS. 1-3, in the assembled configuration, thecompression ring 42 may be disposed about the first end 46 of the body44 of the filter media 36. In this regard, with reference to FIG. 4, thesecond end surface 76 of the compression ring 42 may be disposedadjacent to the first end 46 of the body 44 of the filter media 36. Insome implementations, the compression ring 42 is molded to the filtermedia 36. In other implementations, the compression ring 42 may befastened to the filter media 36 via an adhesive or a snap-fitconfiguration.

As illustrated in FIGS. 2 and 3, the first end 46 of the body 44 of thefilter media 36 may be disposed between the first end surface 74 of thecompression ring 42 and the second end 48 of the body 44 of the filtermedia 36, while the outer side surface 50 of the body 44 of the filtermedia 36 may be disposed radially inward of the outer side surface 78 ofthe compression ring 42. In this regard, the first end surface 74 of thecompression ring 42 may extend proud of the first end 46 of the body 44of the filter media 36 in the axial direction, while the outer sidesurface 78 of the compression ring 42 may extend proud of the outer sidesurface 50 of the body 44 of the filter media 36 in the radialdirection. As illustrated in FIG. 1, in some implementations, the sidesurface 92 of the compression ring 42 is substantially flush with theouter side surface 50 of the body 44. The compression ring 42 may beformed of a rigid or semi-rigid material, such as plastic or metal, forexample. In some implementations, the compression ring 42 is formed froma polyurethane. In particular, the compression ring 42 may be formedfrom a substantially incompressible material, such that the applicationof a force in either the radial or axial direction upon the surfaces 74,76, 78, 80 of the compression ring 42 does not deform the surfaces(e.g., 90, 92) defining the channels 82-1, 82-2, . . . 82-n, orotherwise prevent the flow of fluid through the channels 82-1, 82-2, . .. 82-n during operation of the filter assembly 10.

With reference to FIG. 1, when the filter assembly 10 is in theassembled configuration, the compression ring 42 may directly engage thecover 22 of the housing 18. In particular, the outer side surface 78 ofthe compression ring 42 may directly engage the second support wall 28of the housing 18, while the first end surface 74 of the compressionring 42 may directly engage the first support wall 26 of the housing 18.As illustrated in FIGS. 1 and 4, the diameter D4 of the body 44 of thefilter media 36 is less than the diameter D1 of housing 18, therebydefining an annular passage 94 disposed within the chamber 24 of thehousing 18. In particular, the passage 94 may be disposed between theouter side surface 50 of the filter media 36 and the outer wall 30 ofthe housing 18.

With reference to FIGS. 2 and 4, the plug 43 may be disposed proximatethe first end 46 of the filter media 36. In some implementations, theplug 43 is molded to the first end 46 such that the entirety of the plug43 is coplanar with, or extends proud of, the first end 46. Inparticular, the plug 43 may be disposed on the first end 46 such that noportion of the plug is disposed between the first and second ends 46, 48of the filter media 36. The plug 43 may be formed from one or more of avariety of materials, including plastic, metal, or rubber, for example.In some implementations, the plug 43 and the compression ring 42 areformed from the same material. During operation, the plug 43 preventsfluid from traveling through the center core portion of the filter media36.

During operation of the filter assembly 10, the channels 82-1, 82-2, . .. 82-n of the compression ring 42 may be in fluid communication with thepassage 94. In this regard, the channels 82-1, 82-2, . . . 82-n maycooperate with the housing 18 to define a fluid pathway 96 from theinlet end 12 of the filter assembly 10 to the passage 94. The fluidpathway 96 may include a radial extending portion 98 and an axialextending portion 100 in fluid communication with the radial extendingportion 98. In particular, the end surface 90 of the channels 82-1,82-2, . . . 82-n may be spaced apart from the first support wall 26 ofthe housing 18, thereby forming the radially extending portion 98 of thefluid pathway 96, while the side surface 92 of the channels 82-1, 82-2,. . . 82-n may be spaced apart from the second support wall 28 of thehousing 18, thereby forming the axial extending portion 100 of the fluidpathway 96.

During operation of the filter assembly 10, unfiltered fluid enters thefilter assembly 10 at the inlet end 12, whereby at least some of thefluid may travel through the fluid pathway 96, formed by the channels82-1, 82-2, . . . 82-n of the compression ring 42 and the first andsecond support walls 26, 28 of the housing 18, to the passage 94. Inthis regard, the fluid may travel in a radial direction through theradially extending portion 98 of the fluid pathway 96 and in an axialdirection through the axial extending portion 100 of the fluid pathway96 to the passage 94 prior to flowing through the first end 46 and thesecond end 48 of the filter media 36.
